So why is the atmosphere pushing you down?

Because of the law of gravity.  (so easy)

When was the last time you/anyone did something where the law did not work as required?


Watch to the end - gravity pulls it down as it always does.

Now you'll ask why the bottom hovers before falling.  Same reason your car rides smooth on a bumpy road - tension.

When the energy in the slinky tension is exhausted, gravity wins.  Gravity always wins.
